You need a 64 bit OS to use all your memory.

Why would you buy a 32bit version of Windows 7??

Secondly why would you mix 1600mhz and 1333mhz memory? You know the 1600 will only run 1333 right? You also need to make sure the timings and voltages are the same.

Makes no sense to me.

^ There's your answer Amit1675. Upgrade to a 64 bits OS and please don't mix your RAM.
